PATENT WILLIAM B. WOLF, OF \VALNUT, ILLINOIS, ASSIGNOR OF ONE-UALF TO ISAAC KELLY, OF SAME PLACE.

CHECK-ROWER.

SPECIFICATION forming part of Letters Patent No. 247,727, dated September 27, 1881.

Application filed February 28, 1881.

.T 0 all whom it may concern:

Be it known that I, WILLIAM B. WOLF, a citizen of the United States, residing at VValnut, in the county of Bureau and State of Illinois, have invented certain new and usefulImprovetnents in Check-Rowers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon. which form a part of this specification.

My invention has reference to an improvement in cheek-rowers for corn-planters, and relates more particularly to a novel pulley to engage and to be actuated by the usual knotted rope or wire, and also certain new devices between such pulley and the seed-discharging mechanism of the seed-hoppers, by which the partial rotations of such pulley are communicated to the seed-discharging plates of the seed-hoppers.

The invention, as shown, is intended for application to the well-known two-horse cornplanter, which plants two rows at the same time. As the general construction and material parts of such planters are well known in the art, I do not deem it necessary to exhibit or describe the same any further than to show the mode of attaching my invention.

In the drawings, Figurc'l is arear elevation of a machine embodying my invention. Fig. 2 is a detached view of the lower face of the crank-wheel L and the upper side of the slotted plate 0. Fig. 3 is an end View of the pulley D.

Fig. l exhibits the general frame-work and construction of my invention, and, as there (No model.)

shown. The pulley D proper is placed loosely on the shaft 0, so as to revolve thereon. On

each side of the pulley D is affixed rigidly to the shaft 0 the clutch P, having the four points a, which latter extend beyond the periphery of the pulley D, and are adapted to engage and be operated by the ordinary knotted rope or wire, which is stretched across the field parallel with the line of the movement of the planter. Near the center of the shaft 0 is rigidly affixed thereto the vertical bevelwheel E, which engages the smaller horizontal bevelwheel F, the latter beingattached rigidly to the upper end of the vertical shaft G. The shaft G is journaled through the cross-plate H. To the lower end of the shaft G is rigidly atfixed the crank-wheel L, on the lower face of which is the crank or wrist pin M.

N is the ordinary reciprocating bar, which extends from one seed-hopper to the other, and actuates the seeding devices in and below such hoppers.

O is a plate fixed transversely on the bar N,near the center of the latter, and having the slot d lengthwise in its upper surface. The

wristpin M is fitted to engage the slot at of the gives one motion to the bar N and drops one hill'of corn from each of the seed-hoppers. The knots upon the cord or wire are such distance apart as it is desired the hills of corn may be between the check or cross rows.

The sizes ofthe pulley D, clutch P, and wheels E and F may be varied; but the proportions mentioned will need to be observed.

The pulley D has a groove extending around its periphery to carry the knotted cord. The object in having the pulley D revolve independent of the clutch P is to avoid the friction of drawing the rope or wire over the pulley, and thus save the wear of both the pulley and rope or wire.

The slot (I may be made with both ends closed; but I prefer the open ends, as thus any dirt falling therein can work out. So a simple crank might be substituted for the crankwheel L; but the latter gives greater strength and more momentum.

Guide-pulleys can he placed in the usual way at the ends of the shalt G, to guide the knotted rope to and from the pulley D.

I am aware that a wheel having a wrist-pin adapted to engage with a slotted guide on the seed slide or dropper for operating the same, and also two disks having lugs with which a knotted cheek-row wire or eord engages, with an intermediate loose pulley, are common in check-rowers, and suchI do not wish to be understood as claiming, broadly, as of my invention.

What I olaimqas my invention, and desire I In testimony whereof I affix my signature 5 my presence of two witnesses.

WILLIAM B. WVOLF.
